摘要： Provided are a method, system, and program for increasing processor utilization. A list of work is divided for processing among a plurality of processes, wherein a process is allocated a part of the list of work to process, and the processes execute in parallel. If a process completes the list of work allocated to the process then the process is made available on an available process queue. Before a process performs any work, the process reads the available process queue and determines if any process is available to share the work. If so, the work is split up between the examining process and the available process. In one implementation, the work involves scanning a cache and if necessary destage data.
摘要翻译：提供了用于增加处理器利用率的方法，系统和程序。工作列表被分配用于在多个处理之间进行处理，其中，处理被分配待处理的工作列表的一部分，并且处理并行执行。如果进程完成分配给进程的工作列表，则可以在可用的进程队列中使用进程。在进程执行任何工作之前，该进程读取可用的进程队列，并确定是否有任何进程可用于共享工作。如果是这样，工作就在审查过程和可用过程之间分开。在一个实现中，该工作涉及扫描缓存，并且如果必要的话，数据传送。

摘要： For a technique for maintaining consistency of data, one or more blocks of data identified by a first structure are copied to form a consistent set of data. While not acknowledging completion of write requests to any blocks of data, a second structure is created, wherein the second structure indicates which blocks of data are modified while the consistent set of data is being formed.

摘要： Provided are a method, system, and program for forming a consistency group of data. A command is received to form a consistency group with respect to data received at a first storage site that is mirrored to a second storage site. A first data structure is provided indicating updates to the first storage site not included in the consistency group that are received after the command and a second data structure is provided indicating updates to the first storage site in the consistency group to be formed. A command is transmitted to cause data copied to the second storage site that is part of the consistency group to be copied to a third storage site. Indication is received when the data in the second storage site that is part of the consistency group is copied to the third storage site.

摘要： Provided are a method, system, and program for forming a consistency group of data. Information is provided on a consistency group relationship indicating a plurality of slave controllers and, for each indicated slave controller, a slave storage unit managed by the slave controller. A command is transmitted to each slave controller in the consistency group relationship to cause each slave controller to transmit data in the slave storage unit to a remote storage in a manner that forms the consistency group. A determination is made as to whether all the slave controllers successfully transmitted the data in the slave storage units that is part of the consistency group to the remote storage.

摘要： Provided are a method, system, and program for establishing a point-in-time copy. A source relationship data structure and target relationship data structure are generated when establishing a point-in-time copy relationship between source and target storage areas, wherein the source and target relationship data structures each include an indicator for each source storage area and corresponding target storage area in the point-in-time copy relationship. The source and target relationship data structures are initialized to set the indicator for each source storage area and corresponding target storage area in the point-in-time copy relationship to a first value. A determination is made that data was written to one target storage area after establishing the point-in-time copy relationship. The indicators in the source and target relationship data structures corresponding to the source storage area and corresponding target storage area to which data was written are set to a second value.

摘要： A target data storage system comprises a peer-to-peer communication link interface for linking the target to a source data storage system, and data storage for storing point in time copy data received from the source via the peer-to-peer communication link interface. Information is established at the target relating logical identification of the point in time copy data to point in time copy data stored at the target and to point in time copy data stored at the source, such that the information references the data storage system having requested point in time copy data. A controller of the target accesses requested point in time copy data at the target if the table indicates that the requested point in time copy data is available at the target; else obtains the requested point in time copy data from the source via the peer-to-peer communication link interface.

摘要： Disclosed is a technique for applying changes back to an original copy of data to reduce an amount of data transferred. A first indicator is maintained for each block of data in a first storage to indicate whether the block of data has been updated in the first storage since the block of data was last transferred to a second storage. A second indicator is maintained for each block of data in the second storage to indicate whether the block of data has been updated in the second storage since the block of data in the second storage was overwritten by a corresponding block of data in the first storage. Upon receiving a reverse restore operation, each block of data in the second storage for which a second indicator has been set to indicate that the block of data has been updated is transferred to the first storage and each block of data in the second storage that corresponds to a block of data in the first storage for which a first indicator has been set to indicate that the block of data in the first storage has been updated is transferred to the first storage.
摘要翻译：公开了一种用于将更改应用于数据的原始副本以减少传送的数据量的技术。对于第一存储器中的每个数据块来维持第一指示符，以指示数据块是否已经在第一存储器中被更新，因为数据块最后传送到第二存储器。维持第二存储器中的每个数据块的第二指示符，以指示在第二存储器中数据块是否已被更新，因为第二存储器中的数据块被第一存储器中相应的数据块覆盖。在接收到反向恢复操作时，第二存储器中的已经被设置为指示数据块已被更新的第二存储器中的每个数据块被传送到对应于第二存储器的第一存储器和第二存储器中的每个数据块涉及第一存储器中已经设置了第一指示符以指示第一存储器中的数据块已经被更新的数据块被传送到第一存储器。

摘要： Disclosed is a technique for reducing an amount of data transferred. A first indicator is maintained for each source block of data to indicate whether the source block of data has been updated in source storage since the source block of data was last transferred to target storage. A second indicator is maintained for each target block of data in target storage to indicate whether the target block of data has been updated in target storage since the target block of data was overwritten by a corresponding source block of data. When transferring data from the source storage to the target storage, each source block of data for which a first indicator has been set to indicate that the source block of data has been updated is transferred and each source block of data that corresponds to a target block of data for which a second indicator has been set to indicate that the target block of data has been updated is transferred.

摘要： Provided are a method, system, and program for managing data. A data request is received to a target track in a relationship, wherein the relationship associates a source track with the target track. A destage request to destage the source track is submitted in response to the data request to the target track, wherein executing the data request to the target track is conditioned on receiving a completion response to the destage request. If the source track is not in cache, then a complete response is returned to the destage request. If the source track was in cache when the relationship was established, then the destage request is added to an Input/Output (I/O) queue for the source track. After the source track is destaged in response to processing the destage request in the I/O queue, the complete response is returned to the destage request.
